Question on sorting a contrib:Table and persistent parameters
Hi,
Just started using Tapestry, and would be grateful for some help, just to
check that I'm
not "working against the framework" so to say. I've got a simple app up and
running, based on
Appfuse (excellent starter for Tapestry / hibernate / Spring, thanks Matt).
Basically, I have two pages (bills and calls), each with a Table component
in it. A row in bills
can be clicked, to display the calls for that bill. This works and brings
back the right data, but
if I use the table component from the browser, say to sort a column on the
calls page, it will
loose the context of the billId that it has retrieved.
I changed the bill page to use an external link, which passed the billId in
the URL, to give,
http://localhost:8080/app/calls.html?sp=l28
and the sorting column URL on the table for example, is
http://localhost:8080/app/calls.html?service=direct&service=1&service=contrib%3ASimpleTableColumnPage&service=tableColumnComponent.linkColumn&sp=Acalls%2FcallFormTable.tableView&sp=Scall.dateTime
I noticed that the billId parameter on the URL is being lost. I then set
billId as a persistent
property of the page, and it worked. Unfortunately, after some reading, I
realised that this
meant the billId was being stored in the HttpSession. Is it possible to make
the DirectLink
of the Table component include the billId, and pass it back to the page?
The reason I ask, is then I could open more than one call list from the bill
page, by right
clicking on each bill I wanted. Currently, using the HttpSession means that
both call windows
will only sorted by the last known billId that was requested in the session.
I was thinking of Hidden parameters, but was unsure if that would work,
since was unsure
how and when to get/set them without a post.
It would be nice if there was some way to specify how the page (or maybe
components
aswell) could be persisted. Hence, could the renderer look at its component
hierarchy,
note that a parameter needed to be persisted on the URL, and ensure each
component
it contained (eg the DirectLink) would be rewritten to include the
parameter.Maybe the
persistent attribute could accept values of "URL" and "Cookie" ?
If anyone could suggest a workaround, that would be great, or let me know
I'm barking
up the wrong tree :)
I've included some source below:
Thanks

That is _exactly_ what Tapestry 3.1 will do :). Unfortunately, that is
still in development at the moment, and will take a while until it is
usable.
Alas, at the moment you are more or less stuck with using a session.
Hidden, combined with LinkSubmit, and FormTable's
tableSessionStoreManager property (see my earlier post for details) is a
possibility to do what you ask, but it won't be too straight-forward...
